[PATCH 053/115] xfs: move xfs_attr_defer_add to xfs_attr_item.c

["Darrick J. Wong" <djwong@xxxxxxxxxx>]

From: Darrick J. Wong <djwong@xxxxxxxxxx>

Source kernel commit: 9713dc88773d066413ae23aa474b13241507a89e

Move the code that adds the incore xfs_attr_item deferred work data to a
transaction live with the ATTRI log item code.  This means that the
upper level extended attribute code no longer has to know about the
inner workings of the ATTRI log items.
